Thanks! Your repo is already in my list of things to try for the display switching part. Unfortunately, display switching via DDC is not supported on my current monitor, so if I want that to work I'll have to find a new one that does support it. I also need it to work with Linux, Windows, and Mac M1 machines. Seems like it might be easier to do send all the DDC commands from the Linux machine, rather than get DDC working on all three.

Yea so getting DDC to work is a huge pain. I had a it working OOTB for the three monitors I had miraculously even though they’re all super old. Then the oldest one started to have a pink hue when it woke from sleep for the first 30-45 min, and I was worried about getting stuck without it so then I went on the hunt for a monitor that supported DDC. The biggest issue is there is no product page for any monitor I could find that ever mentions if it supports DDC. You’re almost guaranteed to get some sorta DDC support for enterprise-type monitors. Consumer facing stuff is a giant gamble. Basically all LGs are out, some support it others don’t. It is entirely dependent on which controller they had on hand when they did that run, so you could have inconsistencies within the same model. Monoprice doesn’t officially support it, but the two monitors I tired from them did…kinda there were some oddities and sometimes it would just crash and I’d have to unplug and wait 30sec to reset it. Along w the fact that they were VA panels made me send them back. Dell and HP appear to be good choices, all the dells I’ve tried support it, tho I’ve only got business dell monitors. The HP gaming monitor I settled on supports it fully, tho it takes like 10 seconds to switch, that might be because of the difference in supported refresh rate between the two computers. I will also add that the HP does support it but it doesn’t always like being told to switch by the computer it’s not currently displaying. Usually it will switch no matter which computer sends the command but there are times it just ignores it if the computer isn’t currently being displayed. Finally I can’t tell if this is a monitor thing or a computer thing, but sometimes (rarely) the monitors will confuse each other and not switch and when you check the error logs it says that there’s an incorrect code on the ddc buffer, only thing to do is power cycle that monitor. All that said, I still think this is a better and cheaper solution vs a full hardware usb+video switch.
